Abstract

Mécanisme sélecteur de vitesses comprenant des tringles de coulissement déplaçables en sens axial et des fourchettes basculantes reliées aux tringles. En déplaçant axialement les tringles, on bascule les fourchettes de façon à amener des douilles dans les moyens de couplage et de synchronisation de la boîte de vitesses. Plusieurs fourchettes basculantes sont montées rotatives dans un support de fourchette commun constitué par deux barres parallèles, écartées l'une de l'autre et orientées en direction de l'arbre de boîte. Application aux boîtes de vitesses de véhicule.
